The Nitrogen Cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have an enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic compounds. Conversion of N2 The conversion of nitrogen (N2) from the atmosphere into a form readily available

The Purchasing Order The purchasing cycle is a cycle that includes a catering business buyer buying products from a supplier. It contains a number of steps that take place whenever an order with a food company is placed which is tracked via documentation and receipts kept with the supplier. This is necessary so the supplier can keep track of their food products and how much money they take in and spend. If they didn’t have a cycle then the supplier may not even know what the orders are

Hydrologic Cycle March 3‚ 2013 With every year that passes more and more fossil fuels are being released into the atmosphere. Over the past decade‚ climate changes‚ El Niño‚ and the increase in greenhouse gasses are being discussed more as earth friendly groups are trying to make the public aware of the negative situations the earth is facing. What would happen to the hydrologic cycle if the earth’s climate continues to get hotter? Is it too late to change humans’ patterns of behavior and

contractions and expansions of an economy’s real output over time are inevitable. And while these fluctuations are the result of natural interactions between sellers and buyers‚ government intervention also affects these intervals. The business cycle is unavoidable because‚ in part‚ it is the economical representation of a volatile element: human psychology. In the example above‚ consumers are predictable. But we all know consumer preferences and their senses of well-being change‚ sometimes overnight

The earth has a limited amount of water.That water keeps going around and around and around in what we call the "Water cycle".It is the only way that Earth can be continually supplied with fresh water.The sun is the most important part of renewing our water supply.It can be solid (ice)‚a liquid (water)‚ or gas (water vapor). Water on earth is always changing. How do these changes happen? It is made up of a few main parts:evaporation (and transpiration)‚condensation and precipitation. Evaporation

The Calvin Cycle By: MJ Pineda The Calvin Cycle is basically a part of photosynthesis where plants take in carbon dioxide and uses ATP and NADPH to make sugars from the CO2 and water for the plant to use or for animals to eat. It does not require light‚ and is interestingly called the "dark cycle" 1. The first step of this cycle consists of A carbon atom from carbon dioxide molecule will enter the cycle and joins with a five carbon molecule that is present. 2. The six carbon molecule that
